actuator.
Design and principle of
operation
The electropneumatic Ex d positioner is
mounted on pneumatic control valves. It is
used to assign the valve stem position (controlled variable x) to the control signal (reference variable w). The electric control signal received from a control system is compared to the travel or rotational angle of the
control valve, and a signal pressure (output
The positioner basically consists of an electrical travel sensor system (2), an analog i/p
converter (6) with downstream air capacity
booster (7) and the electronic unit with a
microcontroller (5).
In case of a system deviation, the actuator is
either vented or filled with more air. The signal pressure supplied to the actuator can be
limited to 1.4 bar, 2.4 bar or 3.7 bar by

Design and principle of operation
software or on site at the positioner. A constant air stream to the atmosphere is created
by the flow regulator (9) with a fixed set
point. The air stream is used to purge the inside of the housing as well as to optimize
the air capacity booster (7). The i/p converter (6) is supplied with a constant upstream pressure by the pressure regulator
(8) to make it independent of the supply
pressure.
All parts are enclosed in an Ex d housing.
The electrical wires are connected over a
separate terminal compartment which is also
designed with Ex d protection.
The extended EXPERTplus diagnostics are integrated into the positioner. It provides information on the positioner and generates diagnostic and status messages, which allow
faults to be pinpointed quickly.
The positioner is suitable for the following
types of attachment using the corresponding
accessories:
Direct attachment to SAMSON
Type 3277 Actuator: section 4.1
Attachment to actuators acc. to
IEC 60534-6 (NAMUR): section 4.2

3.1
Additional equipment
Forced venting
The i/p converter stops working if the operating voltage supply to the relevant terminals
is interrupted. The positioner can no longer
operate and the control valve moves to the
fail-safe position (SAFE) determined by the
actuator, independent of the reference variable.
Binary contact
The positioner has three internal binary signals which can be analyzed over terminals
A/B/C. Two of these signals are intended
for the valve end positions and one signal
for a collective fault alarm. The assignment
of these signals to the A/B/C terminals is
determined over Code 25.
Position transmitter
The position transmitter (13) is a two-wire
transmitter and issues the travel sensor signal as a 4 to 20 mA signal processed by the
microcontroller. Since this signal is issued independent of the positioner’s input signal
(min. current 3.8 mA), the actual travel/angle of rotation is controlled in real-time. Additionally, the position transmitter provides
the possibility of signaling a positioner fault
over a signal current of 2.4 mA or
21.6 mA.

Design and principle of operation
Binary input
3.2
The positioner has an optional binary input.
The following actions can be performed over
the binary input:
The positioner is equipped with an interface
for HART® protocol (Highway Addressable
Remote Transducer) for communication purposes. Data are transmitted in a superimposed frequency (FSK = Frequency Shift
Keying) on the existing signal loop for the 4
to 20 mA reference variable.
Either a HART® capable handheld communicator or a computer with FSK modem can
be used to establish communication and operate the positioner.

The switching state of the binary input is
logged.
Set local operation write protection
Settings cannot be changed at the
positioner while the binary input is active. The configuration enabled function
in Code 3 is not active.
Switch between AUTO/MAN
The positioner changes from automatic
mode
(AUTO) mode into manual
mode (MAN) and vice versa.
No action is started if the positioner is in
the fail-safe position (SAFE).
Various diagnostic functions (refer to
EB 8389 EN on EXPERTplus valve diagnostics).
Note: The optional binary output can only
be configured using the TROVIS-VIEW software and over the DD parameters (refer to
EB 8389 EN on EXPERTplus valve diagnostics).
The default switching state is with an open
switch.

3.2.1 Configuration using
TROVIS-VIEW software
Refer to Table 5 on page 33 for order numbers.
The positioner can be configured using the
TROVIS-VIEW software.
The positioner is equipped for this purpose
with an additional digital SERIAL INTERFACE
to allow a computer to be connected over an
adapter cable from the RS-232 or USB port
of the computer to the positioner.
The TROVIS-VIEW software enables the user
to easily set parameters in the positioner
and view process parameters online.
Note: The TROVIS-VIEW software is a common operator interface for various smart
SAMSON devices. The software together
with a device-specific module allow the configuration and parameterization of the device.
The device-specific module for Type 3731-3
can be downloaded free of charge from the
SAMSON website (Services > Software >
TROVIS-VIEW).

case G ¼ threaded connections are required, the connecting plate (6), making sure both seal rings (6.1) are
seated properly.
For double-acting, springless rotary actuators, a reversing amplifier is required to attach the positioner to the
actuator. Refer to section 4.5.
For actuators with a volume of less than
300 cm³, screw the screw restriction
(accessories order no.1400-6964/item
no. 0390-1424) into the signal pressure output of the positioner (or the output of the pressure gauge bracket or
connecting plate).
Place positioner on housing (10) and
screw it tight. Considering the actuator's direction of rotation, align lever
(1) so that it engages in the correct slot
of the coupling wheel with its follower
pin (Fig. 8).

Reversing amplifier for
double-acting actuators
For the use with double-acting actuators, the
positioner must be fitted with a reversing
amplifier, e.g. the SAMSON Type 3710 Reversing Amplifier (see Mounting and Operating Instructions EB 8392 EN).
If a different reversing amplifier (item no.
1079-1118 or 1079-1119) is used, follow
the mounting instructions described in section 4.5.1.
The following applies to all reversing amplifiers:
The output signal pressure of the positioner
is supplied at the output A1 of the reversing
amplifier. An opposing pressure, which
equals the required supply pressure when
added to the pressure at A1, is applied at
output A2.
The rule A1 + A2 = Z applies.
A1: Output A1 leading to the signal pressure
connection at the actuator which opens the
valve when the pressure increases
A2: Output A2 leading to the signal pressure
connection at the actuator which closes the
valve when the pressure increases

WARNING!
Mount the positioner, keeping the following
sequence:
1. Mount the positioner on the control valve
2. Connect the supply air
3. Connect the electrical power
4. Perform the start-up settings
The connection of the electrical auxiliary
power may cause the actuator stem to move,
depending on the operating mode.
Do not touch the actuator stem or obstruct it
to avoid risk of injury to hands or fingers.
5.1
Pneumatic connections
The maximum input pressure (supply pressure) must not exceed 6 bar.
DANGER!
Danger from the formation of an explosive
atmosphere!
The operator of the apparatus must ensure
that the working medium cannot form an explosive atmosphere, i.e. only such gases
may be used which are free from substances
whose presence in the medium might lead to
the formation of an explosive atmosphere
(e.g. do not use flammable gases, oxygen or
oxygen-enriched gases).
34
EB 8387-3 EN
Follow the instructions below to avoid damaging the positioner.
– The supply pressure at the input must
not exceed 6 bar.
– The screw fittings with ¼ NPT thread can
be screwed directly into the positioner.
In case G ¼ threaded connections are
required, the fittings must be screwed
into the connecting plate (6) or pressure
gauge mounting block or connection
block available from the accessories.
Customary screw-in fittings for metal and
copper pipes or plastic hoses can be
used.
– The supply air must be dry and free from
oil and dust.
The maintenance instructions for upstream pressure reducing stations must be
observed.
Blow through all air pipes and hoses thoroughly prior to connecting them.
If the positioner is attached directly to the
Type 3277 Actuator, the connection of the
positioner's output pressure to the actuator is
fixed. For attachment according to
IEC 60534-6 (NAMUR), the signal pressure
can be routed to either the top or bottom diaphragm chamber of the actuator, depending on the actuator's fail-safe action "Actuator stem extends" or "Actuator stem retracts".
For rotary actuators, the manufacturer's
specifications for connection apply.
Connections
5.1.1 Signal pressure gauges
If there are no specifications, calculate as
follows:
To monitor the supply air (Supply) and signal pressure (Output), we recommend that
pressure gauges be attached (see accessories in Tables 1 to 5).
Required supply pressure =
Upper bench range value + 1 bar
5.1.2 Supply pressure
The required supply pressure (of supply air)
depends on the bench range and the actuator's operating direction (fail-safe action).
The bench range is registered on the nameplate either as spring range or signal pressure range depending on the actuator.
The direction of action is marked FA or FE,
or by a symbol.
5.1.3 Signal pressure (output)
The signal pressure at the output (Output 38) of the positioner can be limited to
1.4, 2.4 or 3.7 bar in Code 16.
The limitation is not activated [No] by default.
Actuator stem extends FA (AIR TO OPEN)
Fail-close (for globe and angle valves):
Required supply pressure = Upper bench
range value + 0.2 bar, minimum 1.4 bar.
Actuator stem retracts FE (AIR TO CLOSE)
Fail-open (for globe and angle valves):
For tight-closing valves, the maximum signal
pressure pstmax is roughly estimated as follows:
d 2 ⋅ π ⋅ ∆p
[bar]
pstmax = F +
4⋅A
d = Seat diameter [cm]
∆p = Differential pressure across the valve

HART communication
The positioner must be supplied with at least
3.8 mA current.
A DTM file (Device Type Manager) conforming to the Specification 1.2 is available for
communication. This allows the device, for
example, to be run with the PACTware operator interface. All the positioner's parameters are then accessible over the DTM and
the operator interface.
Note: In the case, complex functions are
started in the positioner, which require a
long calculation time or lead to a large
quantity of data being stored in the volatile
memory of the positioner, the alert “busy” is
issued by the DTM file.
This alert is not a fault alarm and can simply be confirmed.

6.4.1 Dynamic HART variables
The HART® specification defines four dynamic variables consisting of a value and an
engineering unit. These variables can be assigned to device parameters as required.
The universal HART® command 3 (universal
command #3) reads the dynamic variables
out of the device. This allows manufacturer-specific parameters to also be transferred using a universal command.
The dynamic variables of Type 3731-3 can
be assigned as follows in the DD or
TROVIS-VIEW [Settings > Operation unit]:
Write protection
4 The write protection for HART communi-
cation can be disabled over Code 47.
You can only disable or enable this function locally at the positioner.

This locking function can only be disabled over HART communication.

WARNING!
During initialization, the control valve moves

range. Therefore, do not start the initialization procedure while a process is running,
but only during start-up when all shut-off
valves are closed.
Before starting initialization, check the maximum permissible signal pressure of the control valve. During initialization, the
positioner issues an output signal pressure
up to the maximum supply pressure supplied. If necessary, limit the signal pressure
by connecting an upstream pressure reducing valve.

NOTICE
If the positioner is mounted onto another actuator or its mounting position is changed,
reset the positioner to its default settings before re-initializing it. Refer to section 7.7.
During initialization the positioner adapts itself optimally to the friction conditions and
the signal pressure requirements of the control valve.
The type and extent of self-adaptation depends on the initialization mode selected:
MAX maximum range (standard range)
Initialization mode for simple start-up of
valves with two clearly defined mechanical end positions, e.g. three-way valves
(see section 7.5.1)
NOM nominal range

(see section 7.5.2)
MAN manually selected range
Initialization mode for globe valves with
an unknown nominal range (see section

A complete initialization procedure takes
several minutes and requires the valve to
move through its entire travel range several
times. This initialization mode, however, is

The SUB initialization mode is used to replace a positioner while the process is running. For this purpose, the control valve is
usually fixed mechanically in a certain position, or pneumatically by means of a pressure signal which is routed to the actuator
externally. The blocking position ensures
that the plant continues to operate with this
valve position.
By entering the blocking position (Code 35),
closing direction (Code 34), pin position
(Code 4), nominal range (Code 5) and direction of action (Code 7), the positioner
can calculate the positioner configuration.

settings of the status classification are listed
in the code list.
Note: The status classification can be
changed in TROVIS-VIEW and over the parameters in the DD file. Refer to EB 8389 EN
on EXPERTplus valve diagnostics.
To provide a better overview, the classified
messages are summarized in a condensed
state. The following status messages are
available:
Maintenance alarm
The positioner cannot perform its control
task due to a functional fault in the device or in one of its peripherals or an initialization has not yet been successfully
completed.
Maintenance required
The positioner still performs its control
task (with restrictions). A maintenance
requirement or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance
is necessary in the medium term.
Maintenance demanded
The positioner still performs its control
task (with restrictions). A maintenance
demand or above average wear has
been determined. The wear tolerance will
soon be exhausted or is reducing at a
faster rate than expected. Maintenance
is necessary in the short term.

Servicing explosionprotected devices
If a part of the positioner on which the explosion protection is based needs to be serviced, the positioner must not be put back
into operation until an expert has inspected
the device according to explosion protection
requirements, has issued a certificate stating
this or given the device a mark of conformity.
Inspection by an expert is not required if the
manufacturer performs a routine test on the
device prior to putting it back into operation. The passing of the routine test must be
documented by attaching a mark of conformity to the device.

Zero point
Zero point incorrect.
Error may arise when the mounting position/linkage of the positioner moves or when the valve seat trim is worn, especially with
soft-sealed plugs.
Status classification [Maintenance required]
Recommended action Check valve and mounting of the positioner. If OK, perform a
zero calibration over Code 6 (see section 7.6 on page 58).
If the lever position on the back of the positioner has been
changed (e.g. while exchanging the lever), move the lever as far
as it will go in both directions to adapt it to the internal measuring lever.
We recommend re-initializing the postioner if the zero point deviates by more than 5 %.
59
Autocorrection
Should an error occur in the data range of the positioner, the
self-monitoring function recognizes it and automatically corrects
it.
Status classification [No message]
Recommended action Automatic
60
Fatal error
An error was detected in the data relevant for safety,
autocorrection is not possible. This may be due to EMC
disturbances.
The positioner changes to the fail-safe position (SAFE).

x signal
Additional alarm at the fault
alarm output
Determination of the measured data for the actuator has failed.
Conductive plastic element is defective.
The positioner continues to run in emergency mode, but should
be replaced as soon as possible.
The emergency mode on the display is indicated by a blinking
closed-loop control icon and 4 dashes instead of the position indication.
Note on the control:
If the measuring system has failed, the positioner is still in a reliable state. The positioner switches to emergency mode where the
position cannot be accurately controlled anymore. However, the
positioner continues operation according to its reference variable
signal so that the process remains in a safe state.
Status classification [Maintenance required]
Recommended action Return the positioner to SAMSON AG for repair.
63
w too low
The reference variable w is lower than 3.7 mA. This message occurs whenever the power source that drives the positioner does
not comply with the standard.
This condition is indicated on the positioner display by LOW
blinking.
The positioner changes to the fail-safe position (SAFE).
Status classification [No message]
Recommended action Check the reference variable.
If necessary, limit the current source downwards so that no values
below 3.7 mA can be issued.
64

No emergency mode
The travel measuring system of the positioner has a
self-monitoring function (see Code 62).
An emergency mode (open-loop control) is not available for
certain actuators, such as double-acting actuators. In this case,
the positioner changes to the fail-safe position (SAFE) when a
measuring error occurs. During the initialization, the positioner
checks whether the actuator has such a function or not.
Status classification [No message]
Recommended action Merely information, confirm, if necessary.
No further action necessary.
77
Program loading error
When the positioner starts operation for the first time after the input signal has been applied, it carries out a self-test (tEStinG runs
across the display).
If the positioner loads the wrong program, the valve moves to the
fail-safe position. It is not possible to make the valve leave this
fail-safe position again.
